某车型转向系统力矩波动优化

Improvement Design of Torque Fluctuation of the Vehicle Steering System

为实现某车型十字轴万向节转向系统力矩波动优化,通过提取该车型CATIA三维数模中的转向系统关键硬点坐标,利用ADAMS/View软件建立转向系统简化仿真模型,在不改变转向系统安装硬点的条件下,仿真获得了可使转向系统力矩波动最小的传动轴相位角,主观评价及实车验证结果表明,仿真数据优化结果与理论计算结果一致,保证了转向系统力矩波动最小。

In order to optimize the torque fluctuation of the cross-axis universal joint steering system of a certain vehicle model,By extracting the coordinates of key hard points of the steering system in the CATIA three-dimensional digital model of this vehicle model,a simplified simulation model of the steering system is established by using ADAMS/View software.Under the condition of not changing the installation hard points of the steering system,the phase angle of the transmission shaft that can minimize the torque fluctuation of the steering system is obtained through simulation.The results of subjective evaluation and real vehicle verification show that the optimization result of simulation data is consistent with the theoretical calculation result,ensuring the minimum torque fluctuation of the steering system.
